This news on the ban of M855 (green tip) ammo is disturbing. The reasoning is that since it can be used in a pistol (AR pistol that is) it poses a threat to law enforcement because they commonly wear level IIA armour that is defeated by the round. This is of course the tip of the iceberg because nearly all rifle calibers defeat IIA vests. Seeing that they are fired out of AR15s, this effectively opens a ban on ARs. (Not to mention non-AR pistol platforms that we here are aware of that use calibers of equal performance.
